Specification of Letters Patent.

Application filed August 31,1905. Serial No. 276.585.

To wZZ whom, it 721/05; concern.- P Be it known that I, HAROLD EDWARD LORD, draftsman, a subject of the King of Great Britain, residing at Brookfield Villa, 325

Birch Lane, Dukinfield, in the county of Chester, England, have inventednew and useful Improvements in or Relating to Axle- Boxes, of which thefollowing is a specification.

' This invention has reference to improvements relating to the axles and axle-boxes of railway and tramway vehicles and the likev The object of the invention is to enablethe adapted to bear against the end of the top brass or bearing-block.

, through lugs 3 on the two parts.

For the pur ose of lubricating from an oillevel which is ower than the hole in the back of the axle-box the external diameter of the collar is greater thanthat of the body of the main axle in front of the wheel-boss.

Figure 1 of the accompanying drawings shows one construction of axle and axle-box embodying my improvements partly in .central longitudinal vertical section and partly in elevation. Fig. 2 is a transverse vertical section thereof.

The improved axle-box illustrated is suitable for a railway-carriage or railway-wagon or the like.

The axle-box under notice is formed with inwardly-extending flanges and comprises an upper part 1 and a lower part 2, fitted and secured together by means of bolts 7), passing The lower part 2 is formed with an internal flange 4- to prevent the oil which is supplied for lubr1- eating purposes from being splashed out of the box.

The flanged collar (.5, forming a journal, is secured on the axle c by hydraulic pressure, shrinkage, or other suitable method, the

' sleeve and its flanges fit ting against the metal or lining e of the top bearingf.

The lower portion 2 of the axle-box forms an oil-reservoir into which oil is fed through an inlet-passage 5;, cast in the front portion of the box. The mouth of the inlet-passage 5 is covered by a cap g, held in position by aspring h and screw, and to prevent the reservoir from being overfed with oiland the oil escaping at the back of the axle-box the lower edge ofsuch mouth is lower than-the lower edge of the opening in the back of the axle-box through which the axle 0 passes.

As the axle c rotates the collar d, revolvin with it, takes up oil from the reservoir, so that the top bearing is thoroughly -lubricated.

The flanges of the collar are coned on their outer faces, so as to spread oil onto the ends I of the bearing.

The upper portion of the axle-box is formed with inwardly-extending flanges 4?,

arranged to constitute channels 4*, adapted to receive the superfluous oil lifted by the journal and.thrown tangentially therefrom by centrifugal'force, such channels reventing the oil spraying toward the end; of the box and guiding it back into the oil-well.

A groove 6 is preferably formed between the inner flange of the collar (1 and the shoulder 7 of the axle, so as to prevent oil working onto the axle in front of the wheel-boss.

What I claim is 1. The combination with an axle-box having an oil-well of an axle having an improved journal passing into sa d box, said journal being larger than the adjacent portions of said axle and being provided at each of its ends with a flange adapted to feed oil onto the ends of the bearing of said journal, the lower portions of both said flanges-and said journal dipping into said oil-well, substantially as set forth.

2. The combination with an axle-box having an oil-well of an axle having an improved journal passing-into said box, said journal being larger than the adjacent portions of said axle and being providedat each of its ends with a flange that is coned on its outer face and adapted to spray the oil'againstthe ends of the bearing-block of said journal, the oil rising up the cone through centrifugal force, the lower portions. of both said flanges and said journal dipping into said oil-well, substantially as set fort 3. The combination with an axle-box having an oil well and inwardlyextending flanges, of an axle having a journal passing into said box, said journal being larger than the adjacent portions of said axle and being provided at each of its ends with a flange the lower portions of both said flanges and said journal dipping into said oil-well, the in- ICC {vainly-extending flanges of said axle-box beingi arranged to form channels adapted to receive the superfluouoil lifted by said journal and thrown tangentially from the jour nal-flanges by centrifugal force and adapted to prevent the oil of the axle-box and guide it back 'to the oil- Well, substantially as set forth.

4. The combination with an axle-box having an oil-well and inwardly-extending flanges adapted to control the splashing of oil therein of an axle having a journal passing into said box, said journal being larger than the adjacent provided at each of ends with a flange that is coned on its outer face, the lower portions of both said flanges and said journal dipping spraying toward the endsportions of said axle and being .into said oil-well, the inwardly-extending flanges of said axle-box being arranged to.

form channels adapted'to receive the superfiuous oil lifted by said journal and thrown tangentially from the journal-flanges by centrifugal force and adapted to prevent the ,oil spraying toward the ends of the axle-box and guide it back to the oil-Well, substantially as set forth.

In testimony whereof I have signed my name to this specification in the presence of two subscribing witnesses.
